s claims.V (cl. z-zo) (Granted under the act of March 3, 1883, as

amended April 30, 1928; 370 O. G. 757) This invention relates to sewingdevices and more particularly to a new and improved palm for theprotection of the hands during sewing operations. Its intended use is torende-r the forcing of a relatively large needle through two or moreplies of canvas, leather or other material to be sewed together.

In the prior art it has been the practice to employ protecting devicesfor workers hands wherein a relatively flexible pad was adapted to beengaged by the tool employed. In the present invention a protecting padis formed from substantially rigid material which will not materiallydeform in use and will aord a greater degree of protection for the user.

In the embodiment herein illustrated this member is shown applied to asail makers palm which serves to protect the hands during sail making orrepairing operations. Of course other uses of the present invention willbe apparent to persons skilled in the art and it is not desired to belimite-d thereto.

It is an object of the present invention to provide a single, practicaland easily manufactured protecting device for the hands.

Another object is to provide a protecting device which is substantiallynon-deformable and will afford maximum protection.

Still another object is to provide a hand pro- .y

tecting palm which is readily formed fromv rigid sheet material whichwill be light and strong in construction.

Another object of one embodiment of the present invention is to providemeans for engaging the end of a tool and preventing slippage thereof. f

those parts in contact with the thumb, iingersy and palm, rounded forthe comfort of the operator. A metal disc of lead, aluminum, brass orthe like relatively soft metal is inserted therein. The insert isconcave in its operating face in order to prevent the needle fromslipping to one A side when pressure is exerted.

These various features are illustrated in the accompanying drawing inwhich:

Fig. 1 is an elevation of the device, and

Fig, 2 is a section taken along section line 2-2 of Figure 1 partly inelevation and partly in section.

In Figs. 1 and 2, the plastic plate is represented by I. This plate hasa curved notch for the thumb of the operator cut out as at 2. Anextension neck or arm of the main body of the plate, co-planar therewithas shown at 3, is curved around to t the back of the index and middlefingers of the hand of the operator thereby assisting in holding thedevice in position. At 5 is shown the curved edge o-f the plate whichlits along the inside surface of the lingers. 6 indicates the metalinsert, the exposed face of which is concave as shown in Fig. 2.

It is to be understood that by merely having the metal insert project toeither the front or rear surface of the body plate determines whetherthe device is for right or left handed operation. In the embodiment asillustrated the device is for right handed operation.

Various changes inthe shape of the device may be made without affectingthe function thereof or without departing from the spirit of theinvention or the method of use.

The operation of the device consists in grasping it firmly in the hand.The thumb rests in notch 2, the back of the index and middle nger innotches yIl; the base of the fingers or the edge of the palm of the handrests along curved surface 5. The metal insert 6 is brought into contactwith the head of the needle and the latter is easily forced through thematerial to be sewed.

This invention may be made or used by or for the Government of theUnited States for governmental purposes without the payment to me of anyroyalties thereon or therefor.

What is desired to be secured by Letters Patent of the United States is:

1. A hand sewing device for protecting the hands during sewingoperations comprising a body of substantially non-deformable plasticmaterial adapted to be grasped by the user, said a body having anintegral, co-planar finger fitting portion extending therefrom.

2. A hand sewing device for protecting the hands during the sewingoperations comprising a body of rigidplastic material, and a metallicinsert in said body, the whole being adapted to be grasped by the userand said body having an integral, co-planar finger tting portionextending there-from.

3. A hand sewing device comprising a plastic plate including a metallicdisc inserted therein,

said plate having an integral, co-planar iinger fitting portionextending therefrom.

4. A hand sewing device comprising a rigid plastio plate including arelatively soft metallic insert therein, said plate having an integralscoplanar finger tting portion extending therefrom.

5. A handsewing device adapted to function -as a thimbleto force yaneedle through material being sewed comprising a plate portion adaptedto t the palm of the hand; a portion, integral and co-planar with theplate, extending therefrom to the back of the fingers, adapted to t thebacks of certain of the fingers and a relativelysoft metallic discinserted in the plate adapted to impinge Yfingers and a relatively soft,concave metallic disc inserted in the plate adapted to impinge uponthe'needle in forcing it through the material beingsewed.
